DEMOS & TOOLS:

PixLabeler pixel-level labeling of document image content

WHAT: a program that enables pixel-level labeling of document image content; foreground markings in user-selected regions (by enclosure, by brushing, or point-and-click) are colored according to label type

HOW: combines customized user interface design with background processes that possess knowledge of structure in document images; applies line art recognition and connected component analysis to form groups of pixels that can be selected by point-and-click; also supports bootstrapping by existing automatic labeling algorithms
